It's about one-six-thousand-five-hundredth as tall as Mount Everest
In other words, 23 nails is 0.000148545 times the height of Mount Everest, and the height of Mount Everest is 6,731.970 times that amount.(a.k.a. Mount Chomolungma, a.k.a. Sagarmatha, a.k.a. Mount Qomolangma, a.k.a. सगरमाथा, a.k.a. Chajamlungma, a.k.a. ཇོ་མོ་གླང་མ, a.k.a. 珠穆朗玛峰, a.k.a. Zhūmùlǎngmǎ Fēng) (Sagarmatha Zone, Nepal and Tibet, China) (to summit, excluding snow depth)
Mount Everest rises 154,836 nails above sea level at its summit. The plate tectonics of the Indian subcontinent continuously alter the mountain's peak â€” raising it by 0.0699913 nails and shifting it to the northeast by 0.0787402 nails each year.
It's about one-seven-thousandth as tall as a Mauna Loa
In other words, 23 nails is 0.0001434 times the height of a Mauna Loa, and the height of a Mauna Loa is 6,974 times that amount.(Hawaii) (Hawaiian island volcano) (total height from seafloor)
Mauna Loa, one of the five volcanoes which forms the island of Hawaii and the tallest mountain in total height in the world, rises to 161,000 nails above the seafloor. The peak of Loa is home to the approximately 6,000 sq. m (0.6 ha) Lake Waiau, one of the highest altitude lakes in the United States outside of Colorado.
It's about one-eight-thousand-five-hundredth as deep as The Challenger Deep (Marianas Trench)
In other words, 23 nails is 0.00012057 times the depth of The Challenger Deep (Marianas Trench), and the depth of The Challenger Deep (Marianas Trench) is 8,293.90 times that amount.(near Marianas Islands, a.k.a. Ladrones Islands, northwestern Pacific Ocean) (depth below sea level)
The Challenger Deep, at the southern end of the Marianas Trench, reaches a depth of 190,760 nails below sea level. The first manned expedition to the bottom of Challenger Deep took 4 hours and 48 minutes in 1960. This was the only manned descent to the floor of the Trench until 2012, when director James Cameron made the trip; several other descents have been made since then.
It's about one-eight-thousand-five-hundredth as tall as Maxwell Montes
In other words, the height of Maxwell Montes is 8,300 times 23 nails.(Ishtar Terra, Venus)
Maxwell Montes rises to a total height of 190,000 nails. Since Venus does not seem to have the kind of tectonic activity which gives rise to mountains on Earth, the origin of the Venusian mountain remains the subject of some dispute.
It's about 10,000 times as tall as a sheet of Paper
It's about 15,000 times as wide as a Strand of Hair
It's about one-twenty-thousandth as tall as Olympus Mons
In other words, the height of Olympus Mons is 20,000 times 23 nails.(a.k.a. Mount Olympus) (Mars)
The tallest mountain in the solar system, Olympus Mons rises to approximately 470,000 nails. The mountain has been known to astronomers since the nineteenth century because it is tall enough to rise above Mars' frequent dust storms.
